Tn7 family transposons that include all of the guide RNA-directed transposons (CAST) are common in bacteria. We now find diverse representatives across archaea, with many in the Asgard group. Reviving an Asgard element confirmed the exciting behaviors of the family #MicroSky #TESky

Very excited about our work from @jordanthesier.bsky.social and @popomicro.bsky.social et al. We find that Tn7 family elements common in bacteria (that include all of the guide RNA-directed transposons, CAST) are also found across archaea including many in the exciting Asgard group! #MicroSky #TESky

My first co–first author paper with the amazing PoPo @popomicro.bsky.social is now on bioRxiv ! 🧬

We found that Tn7-like transposons - known for finding specific insertion sites before they jump - aren’t just in bacteria. They're in archaea distributed across all major superphyla!

A thread from the Postdoc who led the work on bacterial Telomeric transposons. A wonderful collaboration with the Barabas lab. Officially out in the journal today!

popomicro.bsky.social @popomicro.bsky.social · Mar 27

In eukaryotes, some transposons target telomeres; in Drosophila, they even replace them. Peters lab and Barabas group show that bacteria with linear genomes also harbor diverse telomeric transposons.
